原文外掛簡介
ImageCraft is a Bring Your Own Key (BYOK) plugin that generates alt text for WordPress images using Anthropic Claude, OpenAI GPT-4, or Google Gemini. You provide your own API key and pay only for direct API usage — no middleman service, no subscriptions, no per-image credits.
What makes this plugin different?
Most alt text plugins in the directory either route requests through their own paid service or support only a single AI provider. ImageCraft takes a different approach by combining multi-provider BYOK with SEO and WooCommerce awareness:
3 AI providers, your choice — Switch between Anthropic Claude, OpenAI GPT-4, and Google Gemini using your own API keys. Compare quality and cost, and pick what works for your site.
SEO keyphrase-aware generation — Integrates with Yoast SEO, Rank Math, All in One SEO, and SEOPress to pull the focus keyphrase from your posts and include it in the generated alt text. This means your alt text aligns with your existing SEO strategy without manual effort.
WooCommerce product-context generation — Sends product name, SKU, categories, tags, and price as context to the AI, so generated alt text is relevant to the product — not just a generic image description. Includes 3 dedicated WooCommerce tone modes (Product SEO, Product Descriptive, Product Lifestyle) and a custom prompt option.
SEO image audit — Scans your media library and scores alt text quality. Detects missing alt text, generic/placeholder text (e.g. “image”, “IMG_1234”), filename-based alt text, and text that exceeds recommended length.
Encrypted API key storage — API keys are encrypted with AES-256-CBC using your WordPress security salts before being stored in the database.
Additional Features
Scan and filter your media library (by date range, file size, alt text quality)

Images are sent only to your chosen AI provider when you trigger generation
No data routed through third-party proxy services
All plugin logic runs on your server
External services
This plugin connects to third-party AI services to generate alt text for your images. No data is sent automatically — requests are only made when you explicitly trigger alt text generation (manually, via batch processing, or if you enable auto-generate on upload).
Data sent: When alt text generation is triggered, the plugin sends the image (base64-encoded) along with a text prompt to your chosen AI provider. No personal user data is sent. Your API key is included in the request header for authentication.
